SOCKET.

i Beit known that l, JOHN Eene, a citizen of the United States, residing at Geary7 in the county of Blaine and State oOklahoma, have -invented certain new and useful 1mprovements in Sockets, or which the following is ,a specication.

This invention relates to drill eXtractors adapted'to provide for conveniently remov ing drill stems from well pipes orpholes.

The primary object of the invention isto provide a device of this character which includes a stem receiving socket having guide means associated therewith for the purpose of engaging the stem and properly guiding the same into the socket for engagement with the gripping means carried thereby. y

, Another object of the invention resides in the provision of means for automatically throwing Ythe guide members into operative position to act as Vfinders for locating and guiding the stem into the. socket.

Another object of the inif'ention resides in the details of construction, combination and arrangement of parts7 wherebyl the device is rendered practical eiiicient and comparatively cheap of manufacture.

In the drawings f 4 Figure 1 is a view in elevation ofthe improved socket.

Fig. 2 is a longitudinal sectionaly view takenthrough the socket in a plane at right anglesV tothat of Fig. 1. A' V;

Fig. 3 is a view of a modified form showing the socket in elevation and the guide members in section to illustrate the manner of attaching the latter.

Fig. 4 isa view taken on the line 4-4 of Fig'. 2.

Referring to the drawings, 1 indicates the socket which is provided. with Vthe usual vertical stem receiving bore'2 opening into the lower end of the socket. Adjacent the upper end ot this bore, the socket is provided with opposite'ly arranged side slots indicated at 3 in which are mounted suitable gripping members 4 adapted to engage and clamp the stem as the latter enters the bore 2. These gripping members 4 formno part of the present invention and hence may be of any suit-able standard type used in cop- -rion.

ciated with the pivotsthereoit` to torcefthe members linto proper' engagement with Vvthe the superimposed'ann'ular'shoulders 8 and 9. l Beneath the shoulder and uponopposite i' sifdesjofV the socket 4are. formed two' pairs of ears indicated respectivelyvby the numerals 10 and 11. Pivoted between the ears l0 by:

means of the pivotboltjl2 is an ear 13 car# ried by the upper end Vof f the swinging guard member l4.` `This guard member 14 is semi-circular to embrace the reduced vportion 6 and 7 of the sprocket and coperates with a duplicate guard member 15. vThis latter guard fmember isV attached to lthe socket in exactly the same vmanner .being provided at its yupper end with an ear 16 which is pivotally secured between the years l1 by means oi' a pivot bolt 17. Each Vof these guard members is provided uponffits inner face with a semi-circular enlargement lhaving the iupper edge thereofv itting bel neath the annular shoulder 8 and the lower edge thereof beveledas indicatedat 19. At,

the lower edges' thereof the inner faces of these guard members 14 and 15 are also" beveled as indicated at 2O sopas to engage and gradually guidethe stems within the space between the guard members.

of the reduced lower end 6 of the socket are a pair of guide bolts v21. These bolts extend through the members 14 'and 15, as shown in Fig 4 andare equipped at one end with r1`he opposite ends thereof have The heads 22. nuts 23 threadedly'engaged thereon.

inneropposing face'sof these guide members 14 and y15 are recessed tov providefopposing seats 24 and'25 which surround the guide lbolts asshown and are adapted tosupport the springs 26 which embrace the guide bolts and actl upon the seats 24 and 25 to spread the guide members apart 'so that the same will engage the wall of the opening in which the socket is inserted and will thus come into contact with the stem to drive the latter into the bore 2 for engagement with the gripping members 4.

1n the modification shown in Fig'. 3. the sha-pc ct the guide members indicated at 27 and 28 is slight-lv diierent from that previously set forth but the guide members are attached to the lsocket in exactly the same manner. In this form, the guide `members 27 and 28 are made flaring at their lower end, substantially as shown. Each of these Vguide members is made of gradually increasing thickness toward the vupper endV thereof and at a point spaced from said :upper end is reduced to provide an annular to extend beyond vsaid reduced portion in the Vflaring manner indicated. In this form the guide bolts 21 and 22 and the springs cooperating therewithwill lbe also used as intimated, but further description of these parts is deemed to be unnecessary.

In the use of the' device when usingtlie form of socket shown in Fig. 2 it will be evi'- dent that the guide members 111 and 15 will automatically separate when entering the hole due to the action of the springs pro-y vided for this purpose. Thus the beveled edges 2Oy of these members will scrape the wall, ofY the opening or pipein which the socket isinserted and will thus( insure contact with the stem to be extracted. rIhese beveled edges will guide the stems into the space between the guide members and subsequent contact of the stem with the beveled edges. 19 of the enlargement 18 will cause the stem to be guided into the bore 2 in which it will be `grasped by the gripping members In using the smaller socket shownin Fig. 3 the action is substantially the same with the exception that the curved or tapering inner wall of the members 27 and. 28 will guide the stem directly into the Ibore 2 thus doingaway with the necessity of providing therinclined edges 19 and 2O for this purpose. The form shown in Fig. 2 is what might be termed a straight socket.

particularly adapted for use within well holes .of relatively small circumference,

while the form shown in Fig; 3 is adapted for holes ofy wider circumference in which the spread of the membersl 14 and 15 of the first mentioned form might not besuflicient to insure proper engagement with the drill stem.V

The foregoing panying drawings have reference Ato what might fbe considered to be the .preferred or approved form of my iniifention. I desire it to be understoodk that I rmayfmake such changes in vthe construction, lcombiifntionV and arrangement of parts, materials, di-V mensions, etc., as'may prove'eXpedient and description and accomfall within Y the scope of the appended n of the said guide bolts having a springl surrounding the shank of the bolt and engage ingthe opposing faces of the said4 guide members to exerta pressure thereon for forcing the said each other.
